Abstract

Official abstract text for this publication.

Methods including introducing a treatment fluid comprising a solvent-base fluid and a consolidation composition into a wellbore in a subterranean formation, the consolidation comprising, a crosslinking diverting agent, a hardening agent, and a multi-functional epoxy resin, the multi-functional epoxy resin comprising at least three epoxy groups; coating a face of the subterranean formation with the consolidation composition; and at least partially curing the consolidation composition in the wellbore, to reduce production of unconsolidated particulates from the subterranean formation into the wellbore.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method comprising: introducing a treatment fluid comprising a solvent-base fluid and a consolidation composition into a wellbore in a subterranean formation, the consolidation comprising a multi-functional epoxy resin, a crosslinking diverting agent, and a hardening agent, the multi-functional epoxy resin comprising at least three epoxy groups; coating a face of the subterranean formation with the consolidation composition; and at least partially curing the consolidation composition in the wellbore, to reduce production of unconsolidated particulates from the subterranean formation into the wellbore. 2. The method of claim 1 , wherein the multi-functional epoxy resin is present in an amount in the range of about 0.5% to about 40% by volume of the consolidation composition. 3. The method of claim 1 , wherein the at least three epoxy groups are glycidyl ether groups selected from the group consisting of an aliphatic glycidyl ether, a cycloaliphatic glycidyl ether, an aromatic glycidyl ether, a polyglycidyl ether, and any combination thereof. 4. The method of claim 1 , wherein the multi-functional epoxy resin is selected from the group consisting of glycerol triglycidyl ether; triphenylolmethane triglycidyl ether; 1,1,1-tris(4-hydroxyphenyl)ethane triglycidyl ether; triglycidyl-p-aminophenol; trimethylolpropane triglycidyl ether; 1,3,5-triglycidyl-isocyanurate; (R,R,R)-triglycidyl isocyanurate; isocyanuric acid (S,S,S)-triglycidyl ester; glycerol propoxylate triglycidyl ether; N,N-diglycidyl-4-glycidyloxyaniline; 2,4,6-tris(oxiranylmethoxy)-1,3,5-triazine; triglycidyl-m-aminophenol; triglycidyl-4-amino-m-cresol; triglycidyl-5-amino-o-cresol; pentaerythritol tetraglycidyl ether; 4-(3,3-dihydroxy-2,4,4-trimethyl-2H-1-benzopyran-2-yl)-1,3-benzenediol glycidyl; tris(4-hydroxyphenyl)methane triglycidyl ether; N,N-diglycidyl-2-chloro-4-[2-chloro-N-glycidyl aniline methyl]aniline; tetrafunctional o-glycidyl resin; tetraglycidyl-4,4′-methylenediamine; tetraglycidyl-4,4′-dimethyldianiline; N,N,N,N′-tetraglycidyl-m-xylenediamine; tetraglycidylmethylenedianiline; and any combination thereof. 5. The method of claim 1 , wherein the at least three epoxy groups are disposed symmetrically or asymmetrically in the multi-functional epoxy resin. 6. The method of claim 1 , wherein the crosslinking diverting agent is present in an amount in the range of about 0.1% to about 25% by volume of the consolidation composition. 7. The method of claim 1 , wherein the crosslinking diverting agent is a long-chain amine having a chain length in the range of about 8 to about 90 carbon atoms and having at least one primary amine group. 8. The method of claim 7 , wherein the crosslinking diverting agent is selected from the group consisting of a cocoamine, a cocodiamine, phenalkamine, a dimer amine, a dimer diamine, and any combination thereof. 9. The method of claim 1 , wherein the crosslinking diverting agent is a polymeric amine. 10. The method of claim 1 , wherein the hardening agent is present in an amount in the range of about 1% to about 75% by volume of the consolidation composition. 11. The method of claim 1 , wherein the hardening agent is selected from the group consisting of a cyclo-aliphatic amine, an aromatic amine, an aliphatic amine, an imidazole, a pyrazole, a 1H-indazole, a purine, an indazole, an amine, a polyamine, a polyimine, an amide, a polyamide, a 2-ethyl-4-methyl imidazole, and any combination thereof. 12. The method of claim 1 , wherein the consolidation composition is present in the treatment fluid in an amount in the range of about 5% to about 99.9% by volume of the treatment fluid. 13. The method of claim 1 , wherein the subterranean formation has a temperature of in the range of about 20° C. to about 175° C. 14. The method of claim 1 , further comprising a tubular extending into the wellbore and a pump fluidly coupled to the tubular, wherein the treatment fluid is introduced into the wellbore through the tubular. 15. A method comprising: introducing a treatment fluid comprising a solvent-base fluid and a consolidation composition into a wellbore in a subterranean formation, the wellbore having a length of greater than about 30 meters and exhibiting variable permeability, the consolidation comprising a multi-functional epoxy resin, a crosslinking diverting agent, and a hardening agent, and the multi-functional epoxy resin comprising at least three epoxy groups; coating a face of the subterranean formation with the consolidation composition; and at least partially curing the consolidation composition in the wellbore, thereby reducing production of unconsolidated particulates from the subterranean formation into the wellbore. 16. The method of claim 15 , wherein the at least three epoxy groups are glycidyl ether groups selected from the group consisting of an aliphatic glycidyl ether, a cycloaliphatic glycidyl ether, an aromatic glycidyl ether, a polyglycidyl ether, and any combination thereof. 17.
